To all whom it may concern:

Be it known that I, DANIEL S. VVAUGH, a citizen of the United States,residin at Denver, in the State of Colorado, have invented certain newand useful Improvements in Drill-Steel Holding and Packing cation. I

The present invention relates more partic- Y ularly to chucks for-rockdrills, and especially those known as sinkers and drifter-s,

in connection withwhich fluid is introduced1 into the drill holes forthe purpose of re uo" ing the cuttings-from the working of the drillsteel. The invention, however,i;is

not necessarily limited to this-type of drills.

;.The primary object of the prescnt'invention is-to provide a structurein which'the means in plaoe, and toso efilistruct the means that asimpleform otnup-pecking may be employed, which will not be subjected tothe excessive wear ordinarily occasioned upon packing where drill steelsthat are angular in cross section are employed,

the angular portions of which engage-the packing.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein 1-- Figure 1' is longitudinal sectionalView through a. potion of a rock drilling machine, showing the'iinprovedchuck in place, with-the driil steel therein. Fig. 2 is an end elevationof the same. Figs. 3 and 4: are respeotively, cross sectional views onthe lines I 3-3 end i--4r oft .t.

Q13 in the figures of the. drawings. in the embodimentdisclosed, the motor barrel iifisl llii'iQ/(l by the reference nui, ando eretiug therein is the usual reciprocetery piston (notshown). The endof the barrel inwhieh theohuck is placed is tudinall'y split, as shownat 1*, and has iuced portionl that is threaded. Fit- Specification ofLetters Patent.

' ted into the said end is a chuck comprising sections 7 and 7}. Theinner section 7 extends into the barrel beyond the slits 1, and issnugly fitted therein with a ground joint d0 so that no leakage canoccur. This inner section has abore therethrough that is circular incross section. It is furthernuiar recess of seat 7. The'outer section '7also fits snugly within the end of thebarrel,

and has an outer-tapered end 4=2 projecting preferably squar e, thoughany polygonal therefrom; Tjhi s 'section 7 has a borethere through thstlie-angular in cross, sect-ion,

receives the beveled portion 42 of the outer 1.80

section. This cap. has suitable sockets arneter of the barrel 1.

receive a spanner ring, and the threaded The diameter of the cap 26 Inorder to hold the cap 26 a ainst acci dental displacelnent'and also eeotively secure the chuck sections in place, with the outer section heldagainst rotation in the barrel, a clamping ring 11; is employed that issplit as shown at 11*. This ring engages the inner end of the cap whichit surrounds and also the barre-1., 'Adraw bolt 10 passes transverselythrough the split portion'of the ring, and said bolt also extendsthrough a transverse opening Pin the barrel, and a transversely disposedsocket in. the outer chuck section '17. It will be evident thereforethat when the bolt 10 is tightened, the flange or the cap 26 will bebrought down flush with the outer face of the barrel, and the whole willbe clamped upon thechuck, while the engagement of the draw-bolt 10 withthe outer section of said chuck, positively prevents the rdtationofthesome in the barrel.

In connection with thisstructure, a drill steel 44 is provided. with aldngitudina-l channelsthrough Which-the fluid is carried to ejectcuttings from'the drill hole.

' I Thls drill steel has a portion 46 thalt is angular' in crosssection, said angular portionin the angular conforming to and fitting IThe inner end hereof the chuck section 7 Y 47 of said drill steel iscircular in cross section,'and passes through the packing washerandthrough the inner section 7 of the chuck. II II I -With thisstructure,it will be evident that leakage is effectively prevented and the wear onthe packin socket 7 i nor'cansaid chuck rotatein the I ipartsli lthlisbeingefiectively held against 1 necessary lon'gitii 20 Wlll not 'beexcessive inasmuch as it ears againsta circular surface. However, ifWear does occur, it will be seen that'such -Wear will be taken up by thepressure against the packing Washer, the constituting a pressure chamberin which the fluid may enter, holding said ywasher at all'times againstthe drill steel.

' The said steel fjcannot rotate in the chuck, barrel, the

relative "maria d yet. permitting the al movements of the drill steel. II
